How to Create the Commerce crontab ?
The Magento crontab is the configuration used to run Magento cron jobs.
Magento uses cron tasks that can run with different configurations.
The PHP command-line configuration controls the general cron job that reindexes indexers, generates e-mails, generates the sitemap, and so on.
Starting with version 2.2, Commerce creates a crontab for you.
We add the Commerce crontab to any configured crontab for the Commerce file system owner.
The Commerce crontab is inside #~ MAGENTO START and #~ MAGENTO END comments in your crontab.
To create the Commerce crontab:
1. Firstly, log in as, or switch to, the Magento file system owner.
2. Then, change to your Magento installation directory.
3. Finally, enter the following command:
bin/magento cron:install [–force]
Use --force to rewrite an existing Magento crontab.
Note:
- magento cron:install does not rewrite an existing crontab inside #~ MAGENTO START and #~ MAGENTO END comments in your crontab.
- magento cron:install --force has no effect on any cron jobs outside the Magento comments.
To view the crontab, enter the following command as the Magento file system owner:
crontab -l
